IMPROVEMENT IN PRESSER-FEET FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 100,796, dated March15, 1870.

To all whom it-may concern:

.Be it known that I, WILLIAM W. PETTEE, of Foxborongh, in the county ofNorfolk and State of Massachusetts, have invented an ImprovedSewing-Machine Presser-Foot; and I hereby declare that the following,taken in connection with the drawing which accompanies and forms part ofthis specification, is a description of my invention suflicient toenable those skilled in the art to practice it.

My invention relates to the construction of a guide-foot for guidingcovered wire in a sewing-rnachine in such manner that the wire shall befastened by the needle-carried thread to the work fed beneath the foot,the thread passing through the covering of the wire, my device insurin gthe passage of the needle-point through the covering without contactwith the wire.

My invention consists in combining with a sewing-machine presser-foot aguid e-tube so arrangedwith reference to the needle-throat of the footas to pass through or to open into one side of such throat or. farenough on one side of the needle-path to cause the point of the needle.to take the covering of the wire and escape the wire itself.

The drawing represents a sewing-machine presser-foot and guide-tubeembodying my invention.

A shows a side view of the foot; B, a top view of it; 0, abottom viewthereof; D, a longitudinal section through the wire-guiding tube; E, across-section through the needlethroat; F, a view of one end of thepresserfoot; G, a view of the other end of it; H, a'bottom view, withpart of the foot broken away to show the wire-passage.

a. denotes the presser-foot bar, to which is clamped the shank of thepresser-foot b. At one end of the presser-foot is a tubular projection,0, having running through it a passage,- d, of a diameter justsufficient to allow the covered wire 6 to pass freely through it. Thispassage leads into a groove, f, extending from the needle-throat g tothe opposite end of the foot, and opening out at the bottom of the foot,as seen at G and D, the flat bottom of the presser-foot adjacent to theopen part of the passage resting upon the work h, to which the wire isto be attached, and holding the wire down upon such work. Theneedle-point plays vertically through the center of the needle-hole o rthroat,

and the wire-guiding passage is so far on one 1 side of the throat(where it passes it) that the covering of the wire projects slightlybeyond the center of the throat, orinto the path of the needle-point,the wire itself being beyond the point of the needle. As the needledescends it carries its loop-forming thread through the wire coveringand through the work, forming beneath the work-supporting table the bowor loop to be interlocked with the shuttle-thread, (or with the nextloop of the needle,) the work being fed after the rise of the needle andpreparatory to the next descent thereof, and as the wire and work arethus fed along together the wire is fastened to the Work by each stitchmade by the stitch-formingmechanism,the connection being effected withthe same rapidity with which plain pieces of cloth or other material areunited with an ordinary sewing-machine.

1 claim- A presser-foot having formed with and projecting from itsforward end a tube the bore of which is substantially in line with theneedle-hole, and having a groove on its under side, as shown, whereby acovered wire may be delivered, so that the needle in its descent shallpass through the covering, all as described.
